RESUMO
OBJECTIVES: To investigate the agreement and accuracy of triage blood pressure (BP) in a real-world clinic setting, compared with the reference standard. STUDY DESIGN: Paired triage and standardized BP measurements from patients 4 through 21 years old evaluated in an obesity-related hypertension clinic were obtained via chart-review. Triage BPs were measured by a medical assistant or nurse, often by automated device. Triplicate manual BPs were obtained by the clinic physician. Bland-Altman analyses determined mean differences between paired triage and mean standardized BPs. GEE-based multivariable relative risk (RR) regression determined the RR of triage BP overestimation by ≥ 5 mmHg. Overall agreement, sensitivity, specificity, positive predictive value, and negative predictive value of triage BP measurements identifying hypertensive BP were determined. RESULTS: One hundred thirty participants with 347 clinic encounters were included. Mean age was 13.3 years (SD 3.94), 76% were Black, and 58% were male. Overall mean systolic and diastolic BP difference was 8.7 mmHg (95% limits on agreement: -16.66, 34.07) and 4.1 mmHg (95% limits on agreement: -18.56, 26.68), respectively. Triage systolic BP was more likely overestimated by ≥ 5 mmHg when a large adult (RR = 1.49; 95% CI: 1.00, 2.21) or thigh cuff (RR = 1.94; 95% CI: 1.08, 3.51) was required compared with when a child/adult cuff was required. Overall agreement in identifying hypertensive BP was 57.6%. Sensitivity (52.6%), specificity (63.4%), positive predictive value (60.8%), and negative predictive value (55.3%) were low across all cuffs. CONCLUSIONS: There was poor agreement between usual triage and standardized BP measurements, with potential for significant clinical implications.

OBJECTIVE(S): To evaluate the cross-sectional association of cardiovascular disease risk factors with left atrial (LA) size and function among healthy youth, aged 11-18 years, with a wide range of blood pressures (BPs). STUDY DESIGN: Echocardiographic images of youth enrolled in the Study of High Blood Pressure in Pediatrics: Adult Hypertension Onset in Youth study were analyzed for LA measurements. The association of casual BP, ambulatory BP, and other cardiovascular disease risk factors with LA size and function were determined using descriptive statistics and multivariable regression. Regression models adjusting for age, sex, race, and body mass index z score determined the independent association between ambulatory systolic BP indices (mean systolic BP/50th %ile systolic BP) and BP phenotypes with LA outcomes while exploratory analyses investigated for additional predictors of LA outcomes. RESULTS: The study population consisted of 347 youth: median age 15.7 years, 60% male and 40% non-White. Greater-risk casual systolic BP groups had worse cardiometabolic profiles but no differences in LA size and function. Each 0.1 increase in ambulatory systolic BP day or night index was associated with a 9.9 mL/m2 increase in LA volume/body surface area (LAV/BSA; 95th% CI 2.8-17.0, P = .006) and a 6.8 mL/m2 increase in LAV/BSA (95th% CI 0.8-12.8, P = .03), respectively. Ambulatory hypertension was associated with greater odds of abnormal LAV/BSA, defined as >75th %ile (2014 ambulatory BP monitoring criteria: OR 3.2 [95th% CI 1.4-7.2; P = .002]; 2022 ambulatory BP monitoring criteria: OR 2.1 [95th% CI 1.0-4.1; P = .008]). CONCLUSIONS: Increasing ambulatory systolic BP and ambulatory hypertension are independently associated with LAV/BSA.

[EXTRACTO]. Las enfermedades cardiovasculares (ECV) son la causa principal de la carga de enfermedad en la Región de las Américas que, en el 2017, ocasionó más de dos millones de muertes, una tercera parte del total para ese año. Por sorprendente que parezca, existe la amenaza de que las ECV tengan un impacto aún mayor en los próximos años, en vista de la tendencia al aumento registrada en la última década. La presión arterial (PA) elevada es un factor de riesgo significativo para el desarrollo de las ECV, y causa más de 50% de las cardiopatías isquémicas y de los accidentes cerebrovasculares y 17% del total de muertes a nivel mundial. […] Para abordar la carga cada vez mayor de las ECV, la Organización Panamericana de la Salud (OPS) puso en marcha el programa HEARTS en las Américas, una iniciativa integral de reducción de riesgos que pasará a ser el modelo institucionalizado para el manejo de la hipertensión en la atención primaria de salud para el 2025. Se trata de una iniciativa multinacional, encabezada por el ministerio de salud de cada país participante, con el apoyo de interesados locales y la cooperación técnica de la OPS. […] En este artículo se describe la labor de colaboración entre la OPS, los países ejecutores y los asociados para mejorar el entorno regulatorio relacionado con los dispositivos de medición de la presión arterial en los países que ejecutan la iniciativa HEARTS.

[EXCERPT]. Cardiovascular disease (CVD) is the leading cause of illness burden in the Americas, causing over 2 million deaths in 2017, a third of deaths overall for that year. While striking, CVD is threatening to have an even greater impact in the coming years, based on the upward trend of the last decade. Raised blood pressure (BP), a significant risk factor for the development of CVD, causes over 50% of ischemic heart disease and stroke events and 17% of total deaths globally. […] To address the growing burden of CVD, the Pan American Health Organization (PAHO) initiated HEARTS in the Americas, a comprehensive risk reduction initiative set to become the institutionalized model for hypertension management in primary health care by 2025. It is a multinational initiative, led by the Ministries of Health from each participating country, and with the participation of local stakeholders and the technical cooperation of PAHO. […] This perspective article outlines collaborative work between PAHO, implementing countries, and partners to improve the regulatory landscape related to BPMDs in countries implementing HEARTS.

OBJECTIVES: To assess pediatrician adherence to the 2017 American Academy of Pediatrics' clinical practice guideline for high blood pressure (BP). STUDY DESIGN: Pediatric primary care practices (n = 59) participating in a quality improvement collaborative submitted data for patients with high BP measured between November 2018 and January 2019. Baseline data included patient demographics, BP, body mass index (BMI), and actions taken. Logistic regression was used to test associations between patient BP level and BMI with provider adherence to guidelines (BP measurement, counseling, follow-up, evaluation). RESULTS: A total of 2677 patient charts were entered for analysis. Only 2% of patients had all BP measurement steps completed correctly, with fewer undergoing 3-limb and ambulatory BP measurement. Overall, 46% of patients received appropriate weight, nutrition, and lifestyle counseling. Follow-up for high BP was recommended or scheduled in 10% of encounters, and scheduled at the appropriate interval in 5%. For patients presenting with their third high BP measurement, 10% had an appropriate diagnosis documented, 2% had appropriate screening laboratory tests conducted, and none had a renal ultrasound performed. BMI was independently associated with increased odds of counseling, but higher BP was associated with lower odds of counseling. Higher BP was independently associated with an increased likelihood of documentation of hypertension. CONCLUSIONS: In this multisite study, adherence to the 2017 American Academy of Pediatrics' guideline for high BP was low. Given the long-term health implications of high BP in childhood, it is important to improve primary care provider recognition and management. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03783650.

RESUMO
OBJECTIVE: To assess prevalence of and factors associated with left ventricular diastolic dysfunction (LVDD) in youth with obesity and elevated blood pressure (BP). STUDY DESIGN: This was a cross-sectional analysis of baseline and follow-up visits of 83 youth, 5-21 years, evaluated for overweight/obesity and elevated BP in a multidisciplinary clinic. LVDD was defined according to established adult criteria (LVDDadult; E/A < 1, E/e' > 14, or e'/a' < 0.8) and pediatric criteria (LVDDpeds; E/A <10th percentile, E/e' >99th percentile, or e'/a' <1st percentile) based on data from 103 age-sex matched healthy controls. Baseline factors associated with LVDDpeds were examined using Wilcoxon rank sum and χ2 tests. Multiple logistic regression analyses using generalized estimating equations to account for repeated measures evaluated the associations of adiposity and BP with LVDDpeds. RESULTS: The prevalence of LVDD ranged from 1.2% to 2.7% when we used adult criteria and 19% to 28% when we used pediatric criteria. Those with LVDDpeds were older, predominantly male, and non-African American and had greater weight, BP, BP medication use, and non-high-density lipoprotein cholesterol than those without LVDDpeds. Diastolic BP z score was associated with LVDDpeds by E/A (OR 1.95, 95% CI 1.15-3.32, P = .014) after we adjusted for age, sex, race, BP medications, and body mass index z score. CONCLUSIONS: LVDD was present in a substantial proportion of youth with overweight/obesity and elevated BP using pediatric criteria. Those with LVDDpeds had significantly greater measures of adiposity and BP compared with those without LVDDpeds, and diastolic BP z score was an independent predictor of LVDDpeds by E/A. These data emphasize the importance of prevention and treatment of cardiovascular disease risk factors in childhood.

Hypertension and blood pressure variability (BPV; SD and average real variability) in primary proteinuric glomerulopathies are not well described. Data were from 433 participants in the NEPTUNE (Nephrotic Syndrome Study Network). Hypertensive BP status was defined as previous history of hypertension or BP ≥140/90 mm Hg for adults/≥95th percentile for children at baseline. BPV was measured in participants with ≥3 visits in the first year. Two-hundred ninety-six adults (43 years [interquartile range, 32-57.8 years], 61.5% male) and 147 children (11 years [interquartile range, 5-14 years], 57.8% male) were evaluated. At baseline, 64.8% of adults and 46.9% of children were hypertensive. Histological diagnosis was associated with hypertensive status in adults (P=0.036). In adults, hypertensive status was associated with lower hazard of complete remission (hazard ratio, 0.36; 95% confidence interval, 0.19-0.68) and greater hazard of achieving the composite end point (end-stage renal disease or estimated glomerular filtration rate decline >40%; hazard ratio, 4.1; 95% confidence interval, 1.4-12). Greater systolic and diastolic SD and average real variability were also associated with greater hazard of reaching the composite end point in adults (all P<0.01). In children, greater BPV was an independent predictor of composite end point (determined by systolic SD and average real variability) and complete remission (determined by systolic and diastolic average real variability; all P<0.05). Hypertensive status was common among adults and children enrolled in NEPTUNE. Differences in hypertensive status prevalence, BPV, and treatment were found by age and histological diagnosis. In addition, hypertensive status and greater BPV were associated with poorer clinical outcomes.

OBJECTIVE: To determine whether casual blood pressure (BP) or ambulatory BP monitoring (ABPM) measurements obtained at the initial visit of a child with confirmed hypertension (HTN) might predict left ventricular hypertrophy (LVH), possibly obviating the need for echocardiography. STUDY DESIGN: We conducted a cross-sectional study of 184 children aged 3 to 20 years who were referred for initial evaluation of elevated BP at 3 tertiary care centers. Casual BP and various ambulatory BP variables were analyzed to determine their association with LVH, defined after echocardiography by cardiologist diagnosis or a left ventricular mass index equal to or greater than the sex-specific 95th percentile. RESULTS: A total of 41% of children who had echocardiograms had LVH. Children with LVH were significantly more likely to be non-white and have a higher body mass index z-score. There was no difference in casual systolic or diastolic BP index in children with hypertension who had LVH and children with hypertension without LVH. Children with systolic or diastolic BP loads > or = 50% were no more likely to have LVH than children with loads < 50%. CONCLUSION: LVH is common in children with newly diagnosed HTN. The initial examination of these children should include echocardiography, because neither the severity of casual BP elevation nor the presence of abnormal ambulatory BP results at initial diagnosis are predictive of LVH.
